Question

Simplify the expressions below & write the final in standard form please :)
1.2x^4(4x^2 + 3x + 1)

2.(4x – 3)(2x^2 – 7x + 1)

3.(x^2 + 4x – 3)(2x^2 + x + 6)

Answer 1

Help Please..!

Answer 2

1) = 8x ( 4x^2 + 3x +1)......is this the question?

Answer 3

or id the term outside the brackets 2x^4 ?

Answer 4

*is

Answer 5

Is it 2*4 or 2x*4???

Answer 6

i'm guessing 2x^4.

Answer 7

all three of them are questions.

Answer 8

\[2x ^{4} ( 4x ^{2} + 3x + 1)\]
is this the first one?

Answer 9

@zakiaboo if u don't help us, we can't help u.

Answer 10

yes @ vaidehi that is the first question.

Answer 11

then u just need to multiply the 2 terms and use the indices property :
\[K ^{A} \times K ^{B} = K ^{A+B}\]
I'll do the first one as an example.
\[2x ^{4} (4x ^{2} + 3x + 1)\] = \[2x ^{4}(4x ^{2}) + 2x ^{4}(3x) + 2x ^{4}(1)\]
\[= 8 x ^{(4+2)} + 6x ^{(4+1)} + 2x ^{4}\] \[= 8x ^{6} + 6x ^{5} + 2x ^{4} + 0x ^{3} + 0x ^{2} + 0x + 0\]
this will be the standard form.
